Public phones were available in a handful of post offices and otherwise restricted to major businesses, government agencies, institutions and wealthier residences. Eight million telegrams were sent that year over 43,000 miles of line.
There were around 33,000 phones across Australia, with 7,502 telephone subscribers in inner Sydney and 4,800 in the Melbourne central business district. A trunk line between Melbourne (headquarters of the PMG Department) and Sydney was established in 1907, with extension to Adelaide in 1914, Brisbane in 1923, Perth in 1930 and Hobart in 1935.
During the 1930s the PMG became responsible for the Australian Broadcasting Commission (ABC).
